Abstract
Subsurface imaging is an important topic in environmental geoscience. The objective is to localize and characterize the underlying earth structure of disposal sites, former military or industrial regions up to 50 m depth. Using seismic methods becomes more and more popular in this part of environmental protection. In near-surface seismics the elastic wavefield is excited by a seismic source, e.g. a falling weight or a sledge hammer acting on a metal plate and is sampled by a receiver geophone line array. Contrary to far field applications, the records are dominated by guided Rayleigh surface waves. This type of wave brings information about the upper earth subsurface and is included in the forward modelling procedure. Estimation of environmental parameters is performed by using a broadband maximum-likelihood estimator. The inversion technique is mostly derived from earlier work in underwater acoustics and was successfully applied to parameter estimation in geo-acoustic environments. Here, the method is applied to shallow seismic data measured in a former coal mining area near Bonn, Germany. The objective was to image the subsurface along the horizontal line array to localize a soil densification in this region.
